Modern radars of AESA architecture require very large number of ICs for signal amplification, filtering, AC/DC conversion, digital processing. Then there's precision guided munition, cruise missiles, anti-air missiles, etc with similar requirements. I've seen Russian AESA radar designs with American made Altera/Xilinx FPGA chips and Texas Instrument chips among others. This is the sort of technology that not even China is capable of replacing at the moment, at least not on the state-of-the-art level.

What you saw --- what I posted --- was an AESA board dated around 2007. If it has Altera FPGA dated 2007, then it is something the Chinese would have exceeded long ago. FPGA is also used for prototyping purposes; it does not necessarily mean it will be the chip used on the final product. On the contrary, using FPGA not only is more expensive, but produces more heat and can be slower than hardwired mass manufactured for that purpose ASIC. If you are making prototype radars, using FPGA is fine, but once the radar goes into mass manufacture, each array can have thousands of elements, and at this point, it would make sense to go to ASIC instead.

ICs used in radars and military applications are not necessarily using the smallest nanometer available. On the contrary, trying to use the smallest process possible makes those smallest transistors more vulnerable to interference, cosmic rays and EMP. In fact, when it comes to space applications, satellites and probes, the chips used are those from old processes with the larger transistor size. It is a good idea to keep obsolete semiconductor processes to produce chips for military and space programs.

As a reminder, power ICs do not require or use the smallest nanometer processes. As power circuits, its the opposite. This includes the all important amplifiers.

I saw one of RT documentaries that are showing a special laboratory making modules for radars, and it was a careful hand made process using generics.

You can see the Altera FPGA on the 2007 board, but the phase shifter and the amplifier are all custom made.

In later years, the design has radically changed.

Don't know who sleepy is and couldn't care less. I do think your conspiracy theories are amusing though. Came here for the Type 055 thread and decided to drop by this topic to see what was going on. Was pretty much the shit show I expected it to be.

This will be my one and only reply to you with respect to this issue.

You're the one who came on this thread barging with your ideological bias insisting pretty much that people here buy into whatever bullshit you were selling. I assumed you were a different user I cited based on the mannerism and God complex level arrogance you exhibited with your pompous way of dismissing anything that didn't jive with your infallible analysis.

Then you doubled down with some stupid Uyghur crap that I don't want to get into because we've been already warned not to discuss issues unrelated to the unfortunate situation at hand. And yet you're calling me "conspiracy theorist" lol

But isn't that great news? (As long as they don't collapse ofc).

I am sure you are aware to what extend Russia has been interfering in China's economic/BRI/integration/cooperation projects in Central Asia. That would be huge thorn removed from China

I should note though that we don't want a destroyed or destabilised Russia. China should push for diplomacy when it sees that Russia is at danger of collapse

Seems worst for China, a weaken Russia will likely fall into the "western" camp.

With this invasion Putin has pulled a reverse-Nixon move. He has basically severed any possibility for Russia to become western friendly.

China merely needs to be careful that it doesn't push for excessive benefits and it should be ok

And if Putin is removed, the Communist Party will take power and thus be even closer to China.
I am actually a lot less worried now about Russia's relations with China in the Post-Putin era

Seriously why are shills here already predicting Russia's downfall while in reality, the Ukrainians are getting rekt. You literally fell for their Twitter and reddit brigades reporting their victories that are conspicuously getting ever closer to their largest cities.
This literally reminds me of how the Afghan government can claimed victories after victory vs the Taliban before they literally crammed themselves into the next best landing gear of C-17 to escape the country.

All the Anglos fantasising about regime change in Russia. This isn't the 80s world where American democracy is the shining example for all of the world. America has been taking L's both home and abroad for the last 20 years. American values are failing.

If Russia changes regime, the most likely outcome is a pro Beijing communist party trying to emulate the Chinese model.

A lot of westerners don't know or don't realize that the russian communist party is the leading opposition party, not their anti-semitic poster boy Navalny, nor Pussy Riot nor that nutjob Kasparov.
